If you really wanna reduce the height of the friction plate to fine tune the car, there is still a solution. You may use the F103 C1 and using the F104 C2,C3 and C4 to build the motor mount

me:
Q1 27/5:01 -F103R
Q2 27/5:07 -F104Pro
Q3 29/5:07 -F103R TQ
main 29/5:02 -F103R A-Main 1st

reference:
Q1 28/5:08
Q2 28/5:03
Q3 28/5:00
main 29/5:09 A-Main 2nd

So i assume if I ran the F103R on the second Qualify, the result should be around 28/5:00 to 28/5:06, so currently F104 still a lap slower than the F103R on my hand and still need some work on setup.

I had talk to another driver who also drove a F104Pro
we both agreed on the following
- F104 are more stable at the in-field and easier to pass thru the traffic at the in-field. The reason is the rear is always stick to the ground, it won't spin out even you have a big movement on the steering or change the direction suddently.
- On the stright, it is a different story, it is too sensitive to our steering input, and the full throttle point before the stright are later than the F103R.
- And a funny thing we found on the F104 is, you can brake anywhere you want (an exteme example is full brake, full steering at the end of stright, the car won't spin out like F103)

And both of us think we could have a faster lap if we can true our tires, the F104 tire and wheel is sold out, so we can't try this yet.

i don't have much time to spend on the F104 last weekend, i guess if I put a harder spring at the front, I may able to get a faster lap too

My question is, would it be better to start with the F103 anniversary or jump right into the F104 Pro? Reading some of the posts here lead me to believe that the F104 could have problems in the beginning and may be a little hard to control until hopups are available. My driving skill is a little rusty and will be returning at a Novice/Intermediate level. With a little track time I will be able to run Intermediate level with confidence. Is the F103 Anniversary a more stable car out of the box?

I have a fleet of 103's that will go into retirement after the Nats, if I go to the Nats this year. Im a bit confused how a chassis can lack steering and be twitchy at the same time. I need to get with my hobby shop and get a 104 on order, being out of work at the moment isnt helping my ability to make big purchases either.

Obviously, things can be worked out, but the differences in general layout will produce a tendency toward a certain way of handling.

Tower Hobbies shows it as "coming soon". Seems odd to me; a high wind low RPM motor for a direct drive car?
